Abstract: A catheter-based material removal device includes an elongated tube having a distal material removal tip thereon. The material removal tip includes a one- or two-piece housing affixed to the tube, and a rotating member therein. The rotating member includes a screw thread for coarsely chopping material received within the housing and an outwardly projecting flange for finely chopping the material. The housing includes at least one shearing member located axially adjacent the outwardly projecting flange. The shearing member has a relatively small circumferential size and a shearing edge that removes any material buildup on the axially-facing surface of the flange. Two shearing members may be provided, one each on both the proximal and distal sides of the flange. There may be three flanges restrained within a groove formed with the housing. The shearing members are located adjacent to the groove and may have the shape of teeth, with arcuate inner faces spanning an included angle through the center of the housing of about 25 degrees. The shearing member on the housing extends inward from a lumen wall and the shearing edge thereon has a radially oriented portion and a curvilinear portion blending into tangency with the lumen wall.

Abstract: A low-cost diversity antenna switching system and method is realized by controlling bias voltages on PIN diodes. By increasing the reverse bias voltage impressed upon a PIN diode, an RF signal impressed upon the diode is increasingly attenuated. As the PIN diode is forward biased to conduct in the forward direction, RF attenuation decreases. Two or more PIN diodes are used to increasingly attenuate signals from one antenna as attenuation of signals from another antenna is gradually decreased. The progression of the bias voltages is accomplished using a microprocessor that monitors a received signal strength indicator (RSSI) signal from a radio receiver. The RSSI is used to control which of two antennas are coupled into the receiver by predicting a signal fade.

Abstract: A system for performing gain correction of the image of an object obtained by image capture. A first white image is obtained by image capture at a first time with no object present, and a second white image is obtained by image capture at a second time later than the first image, with no object present. The first and second white images are then compared to determine if they meet predetermined criteria. If the predetermined criteria is met, a third white image is provided based on the comparison of the first and second white images, and the image of the object obtained by image capture is gain corrected based on the third white image.

Abstract: A non-volatile memory system having an array of memory cells with at least one storage element each is operated with a plurality of storage level ranges per storage element. A flash electrically erasable and programmable read only memory (EEPROM) is an example, wherein the storage elements are electrically floating gates. The memory is operated to minimize the effect of charge coupled between adjacent floating gates, by programming some cells a second time after adjacent cells have been programmed. The second programming step also compacts a distribution of charge levels within at least some of the programming states. This increases the separation between states and/or allows more states to be included within a given storage window. An implementation that is described is for a NAND type of flash EEPROM.

Abstract: A digital imaging system includes a color appearance handling capability that utilizes a database including actual image data and information relating to the actual image data to control illumination and color in digital images. The digital imaging system controls illumination and color with a color-by-correlation technology that includes an illuminant detection training algorithm that bases control of illumination and color on a database storing actual illuminants, scenes, and subjects from representative image acquisition devices such as digital cameras and scanners. In one example, illuminant detection training is accurately rendered for a variety of illuminants, scenes, and subjects that are expected to be of interest to users of a particular camera or group of cameras. In the example, the database is formed by user-group submissions from users of a particular camera or group of cameras. The digital imaging system accesses a database capable of supplying actual image data including illuminants, chromaticities, colors, and the like. The database also stores information relating to the actual image data including tags that identify the image acquisition device that acquires a particular image, and information relating to manufacturer, model and version of the image acquisition device, and image acquisition devices settings at the time of acquisition.

Abstract: A low-bit-rate coding technique [502-530] for unvoiced segments of speech, without loss of quality compared to the conventional code Excited Linear Prediction (CELP) method operating at a much higher bit rate. A set of gains are derived from a residual signal after whitening the speech signal by a linear prediction filter. These gains are then quantized and applied to a randomly generated sparse excitation. The excitation is filtered, and its spectral characteristics are analyzed and compared to the spectral characteristics of the original residual signal. Based on this analysis, a filter is chosen to shape the spectral characteristics of the excitation to achieve optimal performance. A low-bit-rate coding technique for unvoiced segments of speech.

A valve seat surrounds the orifice. A valve plunger is disposed within the chamber, an end of the plunger being adapted to sealingly interengage the seat. The plunger is slidably movable between an open and a closed position to open and close the orifice. A fluid inlet and an outlet are disposed within the valve body to deliver fluid to an annular fluid passageway in the chamber adjacent to the valve seat. Fluid is circulated through the annular passageway to cool the valve and a portion of the fluid is expelled through the orifice when the orifice is opened. The plunger is biased into the closed position by a coil spring and movable into the open position by a solenoid actuator mounted atop the valve body. The injector is mounted on an exhaust conduit of an internal combustion engine with the orifice in fluid communication with the exhaust gases. A heat shield surrounding the orifice is interposed between the exhaust gases and the valve body, a radiant heat reflector is positioned between exposed parts of the injector and the exhaust conduit, and an atomizing hook is positioned in a spaced apart relation facing the orifice to control the dispersion characteristics of the expelled fluid.

Abstract: A variable beamsplitter (10) for use with quasi-optical millimeter-wave beams. The beamsplitter (10) consists of a circular metal plate (20) into which a periodic array (30) of rectangular slots is cut. The plate (20) is arranged so that the incident millimeter-wave beam is incident at an angle of 45° relative to the surface of the plate (20). The polarization of the incident beam is parallel to the surface of the plate (20). When the orientation of the plate (20) is such that the electric field is perpendicular to the slots (i.e., the electric field is directed across the narrow dimension of the slots), the plate (20) transmits nearly 100% of the incident power. If the plate is rotated about its axis by 90° (while maintaining a 45° angle between the incident beam and the plate) so that the incident electric field is parallel to the slots, then the plate (20) transmits 0% and reflects nearly 100% of the incident power at an angle of 90° relative to the incident beam. By varying the angle of rotation between 0° and 90°, both the reflected and transmitted power can be varied continuously between 0% and 100% of the incident power.
